I'm showing how I'm using the expandable duffel bag and tie downs to carry some tire changing tools, but it can also be used to carry anything that you might need, such as car cleaning supplies, if you're on a trip or going to a show and shine. The expandable bag will store in it's attached compartment ( ~6" dia X 2" thick) and when not needed , easily stored, along with the two tie downs, in the cars rear storage compartment.
I was only showing my solution to a lack of storage area in the C6, that can also be used for other items. With the duffel bag, you can remove the stored items as a group from your car.
My wording wasn't as clear as it should have been, I wasn't trying to bust your chops. Thanks for posting.
A crash can easily put a 20G on the stuff inside the car. If the bag and contents weigh 20 lbs, that would be a total force of 400 lbs to be taken up by two hooks, 200 lbs each. I don't think the hooks or their mounts are that strong.
On the other hand, I T-boned a moron while driving my 2006. It was a pretty hard hit, fired the airbag and trashed all body work forward of the doors. I had a couple of shotguns and other shooting gear in the trunk, nothing hit me. I suspect that some of it bounced off the seatbacks but can't be sure.
I've tried to figure a way to really secure luggage in case of accident, and just can't find an easy way to do it in the C6.
If someone has a better idea than the OP, please let us know.
I haven't weighed the bag full of tools but I doubt if it's more then 10-12 pounds. The hooks are pretty sturdy, GM designed them to hold the elastic cargo net that is capable of holding quite a bit of stuff. In the case of a hard frontal crash, the elastic tie downs will absorb a lot of the forward energy of the duffel bag when they are being stretched. If the car was T-boned the bag is free to move down the tie downs until the side walls of the rear compartment stopped it's travel, while restraining the bag's forward movement. Even if the hooks failed, or the tie downs, much of the energy would be dissipated prior to the failure. Also the larger, soft, duffel bag would have less of a chance to get past the seat backs, vs a bunch of smaller loose, hard, items. My solution might not be the best, but it's better then just throwing junk in the rear compartment without any means of restraint. Even when one is on a trip with their luggage in the rear full of clothes, etc, securing the bag in place with the elastic tie downs wouldn't be a bad idea. $2.99 for 6 different length tie downs isn't that much of an expense.
